Butterworth active filters are generally preferred over Chebyshev active filters because
A) Butterworth filters are easier to construct.
B) Butterworth filters have higher roll-off rates.
C) the midband gain of the Chebyshev filter is inconsistent.
D) Chebyshev filters have higher roll-off rates.

Question

Quizplus · Accepted Answer

Butterworth filters have a maximally flat passband, meaning that the gain is constant over the passband. Chebyshev filters have a non-flat passband, meaning that the gain varies over the passband. The midband gain of the Chebyshev filter is inconsistent because it depends on the order of the filter.
